In addition, TDMI has a another, perhaps more subtle drawback—when predicting
influence it can be nonzero when two variables have shared history
[1]}. That is, the condition \(I(X_{t};Y_{t+\tau })>0\)  may hold
when variable \(Y\)  is not directly influenced by variable \(X\)  but when either
\(X\)  or \(Y\)  dynamics contains memory of their past configurations.
